This program has come in very handy with my new Work From Home status. I can keep in touch with my coworkers and stay productive. My coworkers installed the program from the source web site. I am using the PortableApps version of the program. I have noticed one issue... Each time I reboot my PC (without first shutting down the LAN Messenger program), the next time I launch the program it says it was shutdown improperly and I have to click OK then load the program again. Could the PortableApps launcher be changed to 'clean up' this file, log, marker, to prevent this error message? I noticed that my coworkers don't seem to be getting this error message when they reboot their PCs. Thank you for this program, and all your PortableApps programs!!!
